Letters Patent No. 84,588, dated December 1, 1868.

I The Schedule referral to in these Letters Patent and making part ofthe same.

To all whom it only concern:

Be' it known that I, A. B. SPIES, of Sterling, in the county oflVhitesides, and State of Illinois, have invented a new and improvedCultivator; and I do hereby declare thefollowing to be a full, clear,and exact description thereof, which will enable others skilled in theart to make and use the same, reference being had to the accompanyingdrawings, forming a part of this specification.

--This invention relates to a new and improved cultivator, for plowingmrcultivating those crops which are grown in hills or drills, and whichcultivators are constrncted in such a manner as to admit of a lateralmovement of the plow-beams, so that the plows may conform to thesinuosities of the rows of plants, and

also be readily raised out of the ground when required,

and held in a raised position while the machine is being drawn fromplace to place.

In the accompanying sheet of (h'awings, v

Figure 1 is a plan or top view of my invention.

Figure 2 is a side view of the same.

Similar letters of reference indicate corresponding parts. i v

A represents an axle, having a pendent crank-arm, B,. at each end of it,and

C O are wheels which are fitted on said arms.

I) is the draught-pole, attached centrally to the axle A.

E is a frame, composed of three bars, a a b, connected by cross-bars c,the side bars a a having an oblique position, so that the front part ofthe frame will be narrower than the rear part, as shown clearly infig.'1.

The sidebars a a have standards 01 cl attached to them, two to each, andthese standards have ordinary shovels or shares F secured to their lowerends.

The rear standards dextend upward above the frame E, and have across-bar, attached to them, which cross-bar serves as a handle.

To the frontend of the central bar b of theframe E, there is attached aclevis, e, in which a link, If, is

V fitted, said link having a roller, I, secured in it,"

This roller is fitted within a metal yoke, J, secured, to the rear sideof the axle A, the front part of the roller working in a slot, f, in therear side of the axle, the yoke J retaining the roller in the slot.

By this mode of connecting the frame E to the axle A, the roller I isallowed to moveor travel thelength of the yoke J, and consequently alateral movement is allowed E and the shovels or shares, in order thatthe latter-may be made to conform to the sinuosit-ies of the rows ofplants.

The frame E is thnsmoved through the medium of a lever,- K, the.fulcrum-pin f of which is in the axle A, said lever being connected tothe frame E by a link, y, and extending back over and beyond the bar Lis a curved bar, attached to the axle A, and projecting backward overthe front part of the frame E.

The upper end of this bar L has a swivel-pulley, M, attached to it, overwhich a rope or chain, N, passes, the front end of the latter beingattached to the front end of the frame E, and-the rear end attachedto abar, 0, pron'ded with a hook-projection, h.

By this arrangement, obstructions may be readily passed over, as thefront part of the frame E may be el avated by drawing back the bar 0,and the front shovels or shares raised out of the ground, the rear onesbeing raised bypnlling upward on the bar G.

In drawing the device from place to place, the shovels orshares may beheld above the surface of the ground, by drawing back the bar 0 andallowing the hook h to catch on the bar G, as shown in red in fig. 2;

Having thus described my invention,

That I claim as new, and desire to secure by Letters Patent,is--

1. Connecting the frame E to the axle A by means of the .roller 1, linkH, yoke- J, and clevis 0, all arranged as and for the purpose set forth.

2. The lever K, applied to the frame E and axle A, in the mannersubstantially as and for the purpose set orth.

3. The curved bar L, attached to the axle A, swivel-' pulley M, clevise, ropeor chain N, and bar 0, all combined and arranged to operate inthe manner substan-- tially as and for the purpose set forth.
